Add debug widget/live activity export and competitor research

Debug features (DEBUG builds only):
- WidgetExporter: Export all widget variants to PNG (light/dark modes)
- Live Activity lock screen export with configurable streak
- Test notifications button to preview all personality packs
- Settings buttons for export and notification testing

Research:
- Competitor analysis docs (Daylio, Bearable, Reflectly, etc.)
- App Store screenshot reference materials
